4-Chloro-2,2:6,2-terpyridine (4-Cltpy, Cltpy, Cl-terpy) is a tridentate ligand that contains a terpyridine (tpy) site with a Cl site at the 4 -position. It coordinates with various metal ions through these two sites to form different coordination polymers. Crystal structure study shows terpyridine unit of Cltpy adopts a trans, trans conformation. Molecules assemble themselves into stacked columns along the b axis, with an interplanar distance of 3.51. It undergoes Williamson type ether reactions with ,-bishydroxy-functionalized poly(propylene oxide). It undergoes Williamson type reaction with -hydroxy--carboxy-functionalized poly(ethylen-oxide) to afford monoterpyridine terminated telechelics.4-Chloro-2,2:6,2-terpyridine may be used in the preparation of the following:mono- and bis-terpyridinesbis-hydroxy-functionalized terpyridine cadmium(II) complex and a fullerene derivative4-functionalized 2,2:6,2-terpyridines, building blocks for novel supramolecular structures, such as double helicates, dendrimers, micelles and metallo-supramolecular polymers
